What's the difference between SR and SRI?
The most effective measure of a roofing material's ability to reject solar heat is the solar reflectance index (SRI), a measure of the constructed surface's ability to stay cool in the sun by reflecting solar radiation and emitting thermal radiation. However, solar reflectance, or SR, is a better way to measure materials that have more thermal mass, including nonroof materials. …
